5 lbs. Plaster of Paris
2 sizes of Mixing Bowls
Reenforcement mesh to stabilize the cast
1 gallon distilled water
Identification tags with string
Gallon baggies (sometimes with Plaster premeasured for quick use)
Kits may also contain Dental Stone, which is thicker than Plaster, and Snow spray, which is similar to hair spray and hardens impressions in the snow before the casting is done.
